Description
Technical field
The utility model relates to a kind of well equipment unit, refers to a kind of rotation hemispheric standing valve especially.
Background technique
There is a unidirectional oiling valve pump barrel lower end of API standard oil well pump, is commonly called as " standing valve ", and this valve is the critical component of oil well pump, in the life-span of its decision pump, is also determining pump efficiency.
Now general " standing valve " that adopts is relatively simple for structure, constitute by valve coupling, valve seat, semispherical valve, valve bonnet and joint, because the oil pumping mud oil later stage, formation condition changes, sand, corrosion thing, saprophytic bacteria, carbon monoxide, sulphide or the like, these mixing cpds that are full of well liquid seriously influence the proper functioning of standing valve.Because the oil well pump of pumping well is in the aboveground work that was not stopping all the time in 365 days throughout the year, so work that standing valve was not also stopping thereupon throughout the year in 365 days all the time, the about per minute of jig frequency of the oil well pump of general pumping well does not wait from four, five times to 14,15 times, calculate for five times by average minimum jig frequency, this valve must be worked 2628000 times in 365 days! The sealing strip of the unavoidable bump ball seat in capital and the semispherical valve of API standard oil well pump whenever rises and falls, in the course of time, the heat that bump produces reduces sealing strip hardness, produce softening, the sand grains that is mixed in the while well, on the inevitable sealing strip such as saprophytic bacteria and magnetic substance attached to valve seat, under semispherical valve constantly clashes into, sealing strip on the valve seat is injured, and loses seal action, and this moment, pump just can not be worked, even if the miscellaneous part of pump all stands intact, because the sealing strip blow-by of fixed valve base causes to stagnate and leaks, pump can't be worked, and must cause oil pumping machine oil pumping to stop operation, must be at least three and stop operation once, five days, at most seven, eight, oil well did not only have output, went back befouling environment simultaneously, stopping well operations is the most vexatious thing of pumping well, and it is few more good more all to wish to stop the well operations number of times! The longer the better to wish the pump life cycle!
Moreover the standing valve of API standard oil well pump pump barrel must have a valve pocket, makes ball that running space not only be arranged, and in the valve pocket certain shoe cream room is arranged simultaneously, and ball valve is opened and made stoste enter shoe cream room, so that can make stoste enter pump chamber when ball valve is closed! The fixedly valve pocket of API standard oil well pump pump barrel has many dead angles, enter stoste in the dead angle and the various impurity in the stoste, inevitable the stagnating gradually of sand scale exists in the dead angle, along with the prolongation of pump work time, stagnating exists the dirty thing in the dead angle in the shoe cream room, layer of sand to get more and more, and arrives to a certain degree, ball valve must be buried, ball valve can not be worked, in the case, even the oil well pump miscellaneous part does not damage, but also take out not fuel-displacedly, must stop well operations!
